The Variation of Main Properties of Different Eucalyptus Clones and the Synthetical Evaluation

The several main properties of 27 three years old clone of eucalyptus were investigated, which were related to the yield. In the process of analyzing the different properties which influence the yield, some methods were used, such as comparison, variontion analysis and relationship analysis. The results showed that there was relationship between the yield and the main properties; there are significant difference and genetic relation among the properties, such as Height and DBH; DBH is the properties which most closely related to the yield, with the index of stem form and unlimited index choose method, the synthetical properties of respect clone were evaluated and excellent clones such as EC1 CH3 CH1 was picked out.
